The correct option is: (c) 2, 1 and 3

Explanation:

Lungs are the organs which actually oxygenate up the blood by exchanging the carbon dioxide to outside and taking up oxygen which comes to them by breathing in by the organism. This oxygen in the blood is then transported to each tissue of the body. Integrated and coordinated works of circulatory and respiratory systems are responsible for this.
